AM50065A33-A Equivalent & Substitute Parts

Part Overview

The AM50065A33-A is a SPST-NO (Single Pole Single Throw - Normally Open) snap-action switch manufactured by Panasonic Electric Works. This chassis-mount switch is rated for 100mA at 125V AC and 30V DC, featuring a lever with roller actuator and solder/quick-connect termination. The product is currently obsolete, making identification of functionally equivalent alternatives essential for design continuity and component sourcing.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the AM50065A33-A requires matching the following critical parameters:

• Circuit configuration: SPST-NO topology
• Switch function: Off-Momentary operation
• Mounting type: Chassis mount with compatible termination
• Actuator style: Lever-based activation mechanism
• Operating temperature compatibility: Minimum -20°C to 105°C overlap
• Mechanical reliability: Minimum 1,000,000 cycle rating
• Electrical classification: EAR99 export control alignment

The Crouzet 83265826 qualifies as a functional substitute based on matching circuit topology, actuator principle, mounting configuration, and export classification. However, electrical ratings differ significantly and must be evaluated against application requirements.

Parameter Comparison

Engineering Selection Recommendations

The Crouzet 83265826 provides functional substitution for the obsolete AM50065A33-A based on matching SPST-NO circuit topology, off-momentary operation, lever actuator design, and chassis-mount configuration. The substitute is currently in active production with RoHS compliance certification.

Selection of the Crouzet substitute requires evaluation of the following differences:

• Current capacity increases from 100mA to 5A, suitable for applications requiring higher switching capacity
• AC voltage rating increases from 125V to 250V, providing broader voltage compatibility
• DC voltage rating is not specified for the Crouzet part; applications requiring DC switching must confirm compatibility
• Operating force reduces from 60gf to 13gf, resulting in lighter actuation
• Mechanical life rating decreases from 10,000,000 to 1,000,000 cycles; high-cycle applications require assessment
• Termination connector size increases from 0.187" to 0.250", requiring PCB or harness modification
• Operating temperature range expands to -20°C to 125°C, providing improved high-temperature performance

The substitute is suitable for applications where the increased electrical ratings and reduced mechanical life do not conflict with design specifications.

Frequently Asked Questions (FAQ)

Q: Can the Crouzet 83265826 directly replace the AM50065A33-A without circuit modification?

A: Direct mechanical and electrical substitution is possible if the application current requirement does not exceed 100mA and the DC voltage requirement does not exceed 30V. The larger quick-connect terminator (0.250" vs 0.187") requires harness or PCB connector modification.

Q: What is the impact of the reduced mechanical life rating in the Crouzet substitute?

A: The Crouzet part is rated for 1,000,000 mechanical cycles compared to 10,000,000 for the original. Applications with cycle counts exceeding 1,000,000 require alternative sourcing or design review.

Q: Is the Crouzet 83265826 suitable for DC applications?

A: The Crouzet part specifies 5A AC rating with 250V AC voltage. DC voltage and current ratings are not provided in the available data. DC application compatibility must be confirmed with the manufacturer.

Q: What are the termination compatibility considerations?

A: The AM50065A33-A uses 0.187" (4.7mm) quick-connect terminals with solder option. The Crouzet substitute uses 0.250" (6.3mm) quick-connect terminals only. Existing harnesses and PCB connectors require replacement or adaptation.

Q: Does the Crouzet substitute meet the same export classification?

A: Both parts are classified as EAR99, maintaining equivalent export control status.

Q: What is the operating force difference impact?

A: The Crouzet substitute requires 13gf actuation force compared to 60gf for the original. This lighter actuation may affect tactile feedback and unintended activation risk in applications with vibration or mechanical shock.
